This is what cryptopia says
4CHN / BTC market is closing
The new updated wallet removed transactions and burned most of Cryptopia balance, Wallet will be reopened once all coins are replaced by the CHAN team.
Do any of the community have to worry about permanently losing their coins? I for one spent over an entire BTC for all my chans. I would really like them to still be there.
I think 4CHN is dying coin now if dev does not do anything about it.
Some devs are like kids. They make coins as projects, then abandons it while developing it. Creating coins should not be just experimental.
